摘要： A resonant test probe for testing high-speed integrated circuit devices. The test probe includes a probe tip that makes electrical contact with a device under test to receive a test signal from the device, and an output circuit transmits the received test signal to a testing apparatus. The test probe also includes tuning circuitry coupled between the probe tip and the output circuit. The tuning circuitry is configured to tune a resonance frequency of the test probe to be substantially equal to an operating frequency of the device under test to enable the test probe to transmit the test signal to the device under test.

摘要： A method of assembling a probe head for a probe card interface is disclosed. The probe head includes a plurality of alignment plates, wherein each of the alignment plates includes a set of holes. The plurality of alignment plates are stacked so that each of the alignment plates is adjacent to at least one other alignment plate and a set of holes in each of the alignment plates is aligned with a corresponding set of holes in each of the remaining alignment plates. A set of probe wires is then inserted through the set of holes, respectively, in each of the plurality of alignment plates. After the set of probe wires are inserted, the plurality of alignment plates are spaced so that none of the plurality of alignment plates is adjacent to another alignment plate. One or more multi-piece spacers may be used to space the alignment plates.
